December: Summer Chop and Hints of Cyclone Swell
December closes the year in summer mode. Average swell height is still 5ft (1.5m), but the period is short at 8.3s. E (18%), ESE (17%), SE (16%) and SSE (13%) supplies the majority of the swell, with a strong ENE (14%) and NE (12%) component from the trade wind belt. Wind is ideal only 37% of the time. NNW (14%) and NNE (13%) are the most frequent directions, but the E-ESE-SE-SSE onshore quadrant totals around 30% and the NE/ENE component adds further texture. Air temps average 23.8°C, water is 23.5°C, and rain increases to 4.21 mm/day as tropical moisture builds. Occasionally a tropical cyclone or monsoon trough in the Coral Sea delivers a solid 6-8ft (1.8-2.4m) pulse, but without offshore wind it often stays lumpy. Pick your windows carefully.
